3x = 54 (divide by 3 on each side)
X = 18
Answer:
11(9 - 2) - 3
Step-by-step explanation:
This is how you write the expression.
Three less means we have a -3.
11 times the sum of 9 - 2 means we have 11(9 - 2)
We put these together to get:
-3 + 11(9 - 2)
Or we can simplify it to:
11(9 - 2) - 3
Answer:
2x^2+4x-30=0
Step-by-step explanation:
2x^2+10x-6x-30=0
2x(x+5)-6(x+5)=0
(2x-6)(x+5)=0
2x-6=0 x+5=0
x=6/2 x=-5
x=3
Use a^2+b^2=c^2.
so u might have two answer one if u plug 17 and 12 as your a and b and solve for c
second is when you plug 12 as a and 17 as 17 qnd solve for b.
hope this helped
